Tramadol is synthetic opioid so it is a narcotic per say(fentanyl, sufenta, alfentanil etc are all synthetic opioids), but is highly receptor specific so there is very little problem with respiratory depression, dependence etc.
The Smithsonian Institution (/smÉªÎ¸ËsoÊniÉn/ smith-SOE-nee-Én), established in 1846 for the increase and diffusion of knowledge, is a group of museums and research centers administered by the Government of the United States.
Stick to a plan: The Smithsonian is an enormous complex, made up of 18 museums, galleries and even a zoo. Although spread across the Washington, D.C., the major museums are centrally located along the National Mall, sandwiched between the U.S. Capitol and Washington Monument.
